Parker 364HB-10PP Barbed Tube Union Tee 5/8 Inch

Product Description

The PARKER 364HB-10PP is a single-barb polypropylene union tee fitting designed for low-pressure fluid and pneumatic tubing systems. It accepts 5/8-inch inside-diameter tubing on all three ports and provides a secure, leak-resistant barbed connection without tools. Built from black polypropylene, the fitting meets FDA compliance and NSF/ANSI 51 standards, making it suitable for food-equipment and potable-water adjacent applications. It handles working pressures up to 125 psi and temperatures ranging from 0 degrees F to 212 degrees F. The overall length is 2.74 inches. Plumbers, HVAC technicians, and equipment service pros install these in tubing runs where a tee branch connection is needed without threaded fittings.

This union tee is used in residential and light commercial fluid-handling applications including beverage equipment, ice machines, water treatment systems, and low-pressure pneumatic lines. Its NSF/ANSI 51 rating makes it appropriate for food-zone equipment where material compliance is required by code. The single-barb profile on each port grips standard flexible tubing and holds under vibration or moderate pressure cycling. It is a practical choice wherever a quick, tool-free tee connection is needed in a compatible tubing run.

Key Features

• Single-barb design on all three ports grips flexible tubing without clamps in low-pressure service
• Polypropylene construction resists moisture, mild chemicals, and corrosion
• FDA compliant and NSF/ANSI 51 certified for food-equipment applications
• Rated to 125 psi maximum working pressure
• Operating temperature range: 0 degrees F to 212 degrees F (0 degrees C to 100 degrees C)
• Compact 2.74-inch overall length fits in tight equipment enclosures

Compatibility

Designed for use with flexible tubing having a 5/8-inch inside diameter and a 0.66-inch outside diameter. Suitable as a replacement or new-install union tee in food-service, beverage, water-treatment, and low-pressure pneumatic tubing systems that require FDA or NSF/ANSI 51 compliant components.

Installation Notes

This fitting is installed by hand — push the tubing firmly over each barb until it seats fully against the fitting body. No thread sealant, clamps, or special tools are required for standard low-pressure service, though hose clamps may be added where vibration or elevated pressure is a concern. Depressurize and drain the system before disconnecting or replacing any fitting. Verify that the tubing inside diameter and outside diameter match the fitting specifications before installation to ensure a proper seal.
